RPSolutions 11.6mm / .457 Hollow Base 156gn – heavy slug for big bore PCP air rifles

The RPSolutions 156gn slug is a big bore projectile in calibre 11.6 mm / .457 with a hollow base profile, designed for high-output PCP platforms. The hollow base improves bore sealing for more efficient gas transfer and stable flight, making it suitable for systems operating from 300 joules upwards. Supplied in packs of 100 pieces.

Construction and materials

Each slug weighs 156 grain and is formed in a hollow base configuration. The mass and base geometry contribute to consistent in-flight stability, retained energy at extended ranges, and reduced wind drift in calm conditions. The relatively heavy projectile profile suits barrels tuned for high muzzle energy.

Application and use

Intended for experienced shooters using big bore PCP air rifles for long-range target shooting and precision work on the range. The hollow base also supports use in pest control scenarios, where its expansion behaviour is comparable to hollow point variants. Pest control with air rifles in the EU is regulated and typically requires a permit or hunting licence.

Integration and compatibility

Compatible with PCP air rifles chambered in .457 / 11.6 mm. Best results are achieved on platforms delivering 300 joules or more. Use of a chronograph is recommended to match velocity to barrel harmonics, as small velocity variations noticeably affect grouping and point of impact at distance.

Maintenance and lifecycle

Store in a dry environment to preserve dimensional consistency. Inspect projectiles before loading to ensure the hollow base remains undeformed for optimal sealing and accuracy.
